Insert rules for logical parent segment B

The insert rules for logical parent (LP) segment B control the insert of LP B using the logical path to LP B.

Note: These rules are identical to the insert rules for PP segment A.
The rules are as follows:
  • To disallow the insert of LP B on its logical path, use the physical insert rule.
  • To allow the insert of LP B on its logical path (concatenated with virtual segment RLC B) use either the logical or virtual rule.
    Where LP B is already present, a logical connection is established to the existing LP B segment. The existing LP B can either be replaced or remain unchanged:
    • If LP B is to remain unchanged by the insert call, use the logical insert rule.
    • If LP B is to be replaced by the insert call, use the virtual insert rule.
